Our invention relates to automatic hopper I vide a feeding device of this characterwhich the machine-operating on thesanie,

of nipples or the like,"and

permits of a verylarge hopper for the stock aving means for' feeding a small number of nipples from the. hopper to the delivery wheel so that they can assume their proper position and be picked upthereby and delivered to the chute, one'at a time-through which they are conveyed to A further object of our invention is to pro- .-vide means whereby the nipples or the like will not be jammed in the chute but will be automatically discharged therefrom when the nipples have reached a predetermined point in the chute, and will be discharged back to the feeding wheel to again be taken up thereand fed to the chute. 4

A still further object of our invention is to rovide automatic means whereby the feedmg of the nipples from the hopper to the elevator wheel is stopped whenl'there are any 'nipples under the oot of the feeler lever and thus provide a simple, cheap andefiective automatic feeder having certain details of structure and combination of parts hereinafter more fully set forth,

In the accompanying drawings Figure l'is a sideelevation partly in sec- 1 tion showing the feeding chute extending'to the drilling fixture of the form shown in the "above mentioned patent.

Referring now to the drawings, 1 represents the drilling fixture which as shown is of the form shown in the above, mentioned pat-I ent, but in this application the control of the nipples was through themedium of the rod 42, while in the present application wheel is 'mounted u Figure 3 is a top plan view, of the drilling p aurouarronorrm tannins navion ma Serial minus.-

ings, and holds it until the lower nipple i's ca'rriedforward. When the first nipple is gushed forward, the second nipple drops own on the pusher bar and is free to drop in front of the bar when the bar moves back., I l.

The clamping, arm 4 is used in upper notches for the two long style nipples and in the lower notch for the short nipple. A spring 5 bears on the outer face of the clamping arm and-held in the position shown in Figure 3 of the drawings. The feeding mechanism issupported by the drill fixture by means of the bracket 6 attached to the frame 7 which is also fastened to the drillfixture at its lower semi-circular frame 8 which as shown has secured thereto a plate 9 carrying the stub axle 10 u on which is rotatably mounted the liftin w eel11. .The outer face of the liftend. The frame -7 carries at its upper end a I ing w eel -11.i s slightlybeveled and engages-- a correspondingly shaped groove 12 in the friction drive wheel 13. This friction drive 11 aidownwardly extending arm- 14 carrie by the frames 7 and 8, whereby the lifting wheel is rotated. The

outer end of the shaft of the'friction fdrive wheel 13 is provided. with a pulley 15 over which a drive belt'16 passes and by means of which the lifting wheel is continuously rotatany desired manner.

The lifting wheel 11 has its inner face provided'. with a semi-circular groove provided with hooks 17 which are of a diameter sufliciently-large notto enter the smaller end of the nipples, but to enter the larger endwhere-" by the nipples can only be lifted when in their proper position. The bracket 14 supports the enlarged hopper 1 8 which is arranged at an incline as indicated at 19, and the extreme lower end thereof is in a plane with the upper edgejofthe semi-circular groove in the inner face of the lifting wheelll. The hopper 18 is provided with a partition 20 having a comparatively small opening in its lower end through which the nipples are fed to the with a vertical plate 23 forming a dam to prevent the nipples from passing downwardly to the lifting wheel. The lower inclined boted, said drive belt being driven by the drill in chute 22 which has its lower end provided the hopper. This elevator is of a size to pass tom 19 of the hopper above the dam or plate 23. is provided with an opening 24 and provided with a guide way'25 extending downwardly in which is arranged an elevator 26 having it: upper face inclined at 27 and arranged at the same angle as the bottom 19 of upwardly through the opening 24, and elevate a small number of nipples upwardly Within the chute 22 until the upper inclined end 27 reaches the upper edge of the partition 23 when they are dropped by gravity down into the semi-circular groove in the liftin "wheel 11, and will be taken up by the hook 1? cut away-portion 29 is the ejector 31, which normally lies in such a position that the nip-' ples are free to pass through the chute. -When the chute has become filled and the lower end of the ejector is forced outwardly, as shown in Figure 1 of the drawings, the upper end of the ejector assumes such a position that as the nipples pass downwardly therethrough they engage the upper end and are thrown outwardly into the hopper and thus there will be no jamming of the nipples in the chute. The lifting wheel 11, at one side, is provided with a stud 32 eccentrically carried by the wheel and to which is pivotally connected the upwardly extending link 40 having a pin 41 at its upper end. The outer end of the pin 41 is provided with a loosely mounted link 42 to which is pivotally connected the inner end of the arm 33. The outer end of the arm 33 is pivoted at 34 to the frame 8, whereby the arm 33 is moved up and down by the rotation of the wheel 11. Mounted on the end of the arm 33 is a lever 35 which carries the relief pawl 36, and the feeler rod 37. The eleva'tor'26-is provided with an upwardly extending rod 38 which carries a collar 39 which is engaged by the pawl 36, and said collar is cut away on an angle where the pawl passes over it whenit is coming down. Thus, it will be seen that if there are any nip )les under the foot 40, the pawl 36 is cause to move out from the collar and the rotation of the lifting wheel will not operate the ele vator, and no more nipples would be fed from the chute 22 to the inclined bottom 19 of the hopper, and allow the nipples on the inclined bottom to not crowd and to assume the proper position in the semi-circular groove in the lifting wheel so that they could be taken up by the hooks in their proper position so as to be properly discharged in the chute.

Having thus fully described our invention what we claim is scribed comprising a stationary hopper, a chute adjacent the hopper, a lifting wheel adapted to lift the nipples from the hopper and discharge them into the chute, and an ejector pivotally mounted on the chute and controlled by the nipples in the chute whereby when the chute is filled with nipples so as to engage the ejector, said ejector is positioned for discharging the nipples delivered by the lifting wheel from the chute.
